Swagger file not present -- Azure Machine Learning

Kutay Acar 11

I am currently training and deploying machine learning models through Azure Devops Pipelines to Azure ML Studio.

When I deploy the model to endpoint through the pipeline to an endpoint I am getting the following error:

    "GET /swagger.json HTTP/1.0" 404 19 "-" "hackney/1.17.4"
Swagger file not present
"GET /swagger.json HTTP/1.0" 404 19 "-" "curl/7.67.0"
Swagger file not present

I have no code related to swagger. So I could not understand.

It was successfully building the endpoint before. It just suddenly popped out.

Are you getting the error when deploying the web service or consuming the web service? It would be helpful if you can also share your deployment steps and configuration (please mask authentication credentials). Thanks.

It is happening when deploying as endpoint. When I look at the deployment logs i get the message "Swagger file not present" I am using examples on github for deployment and inference configs https://github.com/MicrosoftDocs/pipelines-azureml/blob/master/models/diabetes/config/inference-config-withenv.json and https://github.com/MicrosoftDocs/pipelines-azureml/blob/master/models/diabetes/config/deployment-config-aks.yml

Hi, we check for swagger during deployment, but it shouldn't fail the deployment if the swagger isn't present. It's unclear where you're getting this error and what is causing the error. My suggestion is to raise a support request for engineers to perform proper diagnosis of the issue.

I deleted the existing AKS and redeployed a new one.
